Inspector: Display symbol id.
Inspector: Rename absolute coord labels.
blur filter
better test with animation loop (that doesn't animate anything actually) and stats counter
call premultiplyAlpha before blur
malloc/free seem to behave better than char buf[len]
some minor optimizations
disable closure compiler. problems with memory management?
remove map file after build
use .length
wrap lib to prevent global var cluttering
optimize cases where alpha == 0

unsure if i can do that in blur
write 32bit words instead of bytes
Make invisible elements count when calculating their parent's bounds
clean up

- added dat.gui
- put all filters into filters.c
- created Demo class for main app
- made raw asm.js function wrappers publicly available
- removed unpre/premultiply calls from blur()
Override _getContentBounds in TextField to ensure valid dimensions
Set startFrame for default scene.
Fix framesLoaded.
Optimize DisplayObject::_getTransformedRect by returning early when targetCoordSpace is null

This gets rid of 8 property assignments, 1 function call, 4 Math.min/max calls with 4 args each, and one object allocation with 4 properties. In a *very* hot code path.
